The Home Depot Designer - Kitchen/Bath interview questions

Took a lot of patience. Called in for an interview. Called for a second interview and was told they were trying to figure out where I would do them best, Third interview, got an offer. Met with the manager to discuss pay. Offered 15 even though I had asked for 20. Had to do a drug test and then had to wait for the result. It took a while for them to get back with me. So long I was wondering if they had changed their mind.
